【摘要】：目的:探究房颤对微创二尖瓣术后患者的静态肺功能及运动耐量水平的影响。方法:微创二尖瓣术后患者30例,按有无房颤分为两组,各15例,两组间基本情况保持均衡。所有患者在2013年1月1日至2014年9月30日期间进行静态肺功能及症状限制的极量心肺运动测试。肺功能由用力肺活量、第一秒用力呼气量、两者实测值分别占预计值的百分比,及1秒率表示;运动耐量用峰值时公斤摄氧量(peak VO2/kg),表示,通气效率用无氧阈时二氧化碳通气当量(VE/VCO2@AT)表示。结果:房颤组表现为轻度限制性肺通气障碍,而窦律组平均肺通气功能正常;房颤组运动耐量水平显著低于窦律组,两组peak VO2/kg分别为17.34±2.82 ml·kg-1·min-1、20.35±4.13 ml·kg-1·min-(1P=0.03);两组间VE/VCO2@AT也有显著性差异(34.48±4.16 vs 29.80±4.51,P0.01)。结论:二尖瓣术后合并房颤的患者,其肺容积及运动耐量明显低于窦律的患者,运动耐量下降的主要机制为心排血量减少。
[Abstract]:Objective: To study the effects of atrial fibrillation on static pulmonary function and exercise tolerance in patients with level of minimally invasive mitral valve surgery. Methods: 30 cases of patients with minimally invasive mitral valve surgery, according to whether atrial fibrillation were divided into two groups, 15 cases each, two groups basically balanced. Maximal cardiopulmonary exercise test were all static pulmonary function and symptom limited in the period from January 1, 2013 to September 30, 2014. The lung function by FVC, FEV1, respectively. The percentage of predicted value between the measured value, and a second rate; exercise tolerance with peak oxygen uptake (peak kg VO2/kg), said that with the ventilation efficiency of carbon dioxide equivalent ventilation anaerobic threshold (VE/VCO2@AT). Results: AF group showed mild restrictive ventilatory disorder, and sinus rhythm group average normal pulmonary ventilation function; atrial fibrillation group exercise tolerance level was significantly lower than that in sinus rhythm group, two groups of peak VO2/kg were 17.3 4 + 2.82 ml kg-1 + 4.13 min-1,20.35 ml kg-1 min- (1P=0.03); VE/VCO2@AT in the two groups had significant difference (34.48 + 4.16 vs 29.80 + 4.51, P0.01). Conclusion: atrial fibrillation and mitral valve surgery patients, the lung volume and exercise tolerance was significantly lower than that of patients with sinus rhythm the main mechanism of exercise tolerance, decreased cardiac output is reduced.

【正文快照】： 微创二尖瓣手术可在小创伤的情况下进行二尖患者一般资料见表1,两组间年龄、性别、身高、体瓣异常结构的纠正,使得手术创伤对患者的影响减重、体质指数、术后天数无显著性差异。少[1],但是仍有许多患者术后症状改善不明显,伴有1.2方法容易气促、疲劳及运动能力降低的问题[2]。，
